1919
If it's both upside down and reversed from left to right, it would be equivalent to the image rotated 180 degrees.
1961 was the last year that read the same upside down and right side up. After 1961, the next year that will satisfy this condition is 6009.
Yes, a convex lens can produce a real inverted image that is reversed from left to right. This occurs when the object is placed beyond the focal point of the lens. The image is formed on the opposite side of the lens from the object.
The year that can be read right side up and upside down is 1991. When flipped, the digits remain unchanged and still read as 1991. Neither 1990 nor 1999 has that property.
Yes, when you look at something upside down, the image will be projected upside down onto your retina, located at the back of your eyeball. However, your brain is able to interpret the image and flip it right side up so that you perceive the object correctly.
1961
A concave mirror gives an upside down image at a certain distance called the focal point. As you move closer to the mirror beyond the focal point, the image flips and becomes right side up.
Something that looks the same upside down has point symmetry.
He seems to be right handed as he played guitar right handed. As talented as Brad Paisley is though ... he could do it left or right upside down behind his back ;)
You could just go straight
Birds and other animals that fly south during migration follow natural navigational cues such as the sun, stars, and landmarks. They do not need to go upside down because their internal compasses and instinctual behaviors guide them in the right direction. Additionally, flying upside down may not be aerodynamically efficient and could pose risks to their safety.
If it's both upside down and reversed from left to right, it would be equivalent to the image rotated 180 degrees.
1961 can be read the same way right side up and upside down.
it means that if you are looking at a shape of a triangle then will it be able to go upside down looking the same way? well no it wont the point was on top not on the bottum right?
The word "NOON" is an example of an image that reads the same right side up and upside down.
no, they do not.
No, it is an accute angle
